Following her three-month stint on stage, Sienna wrote on Instagram: 'That is an over and out for Maggie the Cat! Exhausted, exhilarated and incredibly emotional to have reached the end after 98 shows.... Yipeeeeee!!!' (sic)

In recent weeks, the fashionista has enjoyed catching up with her former fiancé Tom Sturridge and they have looked like the friendliest of exes on their stroll through New York.

Sienna shares her little girl Marlowe Ottoline Layng Sturridge with her former fiancé whom she dated from 2011 to 2015.

She previously admitted the former flames often stay at each other's houses as part of a bid to give their five-year-old daughter Marlowe a loving family unit.

The Alfie star told Harper's Bazaar: 'Everybody will stay over or we'll all go on holiday and that's because we genuinely want to be around each other.

'It's great for our daughter that she has two parents who love each other and are friends. He's definitely my best friend in the entire world.'

Dramatically different: Sienna cut a casual figure in wide-legged jeans and white trainers, a far cry away from the slinky costumes and glamorous ballgowns preferred by her stage alter ego

The confession came after she broke her silence on the Harvey Weinstein sex abuse scandal after more than 30 women in the film business accused the disgraced movie mogul, 65, of sexual harassment.

Sienna publicly spoke out about the Weinstein scandal, taking to her Instagram account to voice her solidarity with the women affected.

She wrote: 'Having worked many times with the Weinstein Company, I feel compelled to comment on the horrendous allegations that have come to light over the past few days.

'I was fortunate to never have been subjected to sexual harassment or advances by Harvey Weinstein, but I stand in absolute solidarity with those who were.'

She added: 'Emma Thompson put it perfectly when she said, "What we need to start talking about is the crisis in masculinity, extreme masculinity, which is this sort of behavior, and the fact that it is not only ok, but is also represented by the most powerful man in the world right now".'
